A person's belief that their previously successful football club is still universally revered and feared, despite a dearth of competitive success in the last two to three decades. Most applicable to clubs that have been managed by Kenny Dalglish (see Liverpool FC, Glasgow Celtic, Blackburn Rovers et al.).

Scott: Dave, where do you think Liverpool will finish this season?
Dave: I think we'll be challenging for the title, so long as Stevie and Luis stay fit.
Scott: You do realise that Liverpool are currently 12th in the table have won just twice in 10 games?
Dave: Yeah but we're a massive club and the manager will turn it round.
Scott: Dave you are being quite deluded; I think you may have Liverpool Syndrome.
Dave: Not so, Liverpool are the biggest club in the world and everyone's favourite song is 'You'll Never Walk Alone'.
